of the words in the box. (P 99 Activity 6)
Step 4: Language practice
Watch the video and repeat.
Step 5: Practical application
We can do many things to make our school green. Remember the three most important words: recycle, reuse and reduce! Here are my suggestions. Don’t throw away things made of glass, plastic and paper, but recycle them because throwing things away is wasteful. Plastic bags are hard to recycle, so reuse the old ones when you can. Reuse the paper to save trees. Take a cloth bag with you when you go shopping. Walk and cycle more so that we can reduce pollution!
Write a passage on how to make your school greener and give reasons. Try to use because, so and so that. ( P 99 Activity 7 )
Step 6: Homework
1. Review the new words and expressions in today's lesson.
2. Finish the passage about the suggestions to create a green school.
